Starter Interrupt System Circuit

Turn ignition switch to OFF position and disconnect ATS ECU connectors. Unlock either driver's or passenger's door using key. Put shift lever into Neutral or Park position (A/T) or depress clutch pedal (M/T). Turn ignition switch to START position. Ensure battery voltage exists between ground and ATS ECU connector "A" terminal No. 1 (Pink wire). If battery voltage does not exist, repair short or open in starter relay circuit. If battery voltage exists, check ATS ECU. See PIN VOLTAGE TESTS . If found to be defective, replace ATS ECU and retest system.
